Anyone have experience repairing a Hayward sp711-13 multivalve key assembly? Mine seems to be developing tiny cracks in the notches where the key lever fits to select the various settings (backwash, rinse , waste, etc...). It's about 7-8 years old.
I rebuilt the valve (new o rings and spider gasket) and then found the tiny crack was actually where the leaking was occuring. I notice that some of the other notches are beginning to crack, too.
Can I use epoxy inside the valve (inexpensive) to reinforce the key notches, or should I just replace the whole assembly(much more costly)?
What do you guys think?
Thanks in advance for your help!
